Paleokarst of the Bohemian Massif in the Czech Republic: an overview and synthesis

, 1995
Paleokarst of the Bohemian Massif on the territory of the Czech Republic developed as polygenetic and polycyclic forms with several phases of fossilization and rejuvenation depending on tectonic phases and deep chemical weathering.

Differences of carbon and oxygen isotopes in coarse-grained calcite from the Permian Maokou Formation in different regions of Sichuan Basin and their significance in paleokarst environment

Carsologica Sinica
Oil and gas fields in karst carbonate reservoirs are widely distributed in China. A number of karst fracture-vuggy reservoirs have been found in the Tarim Basin, the Ordos Basin and the Sichuan Basin.

Analysis of Paleokarst Sinkholes in the Arkoma Basin using 3-D Seismic

, 2015
Paleokarst features are important to understand, both with regards to research geologists and to the petroleum industry. In terms of geology, understanding paleokarst features can yield more information about the depositional and surface environments of ...

Jurassic Paleokarst in the Ventisquero Unit (External Subbetic, Betic Cordillera)

, 1991
The importance of Jurassic karstification at the top of the Gavilan Fm. (Lower Jurassic) in the Ventisquero Unit (southern External Subbetic) is stated. We have recognized and analysed a significant subaeria/ exposure surface with paleokarst morphologies

Application of Geologically Constrained Machine Learning Method in Characterizing Paleokarst Reservoirs of Tarim Basin, China

, 2020
As deep carbonate fracture-cavity paleokarst reservoirs are deeply buried and highly heterogeneous, and the responded seismic signals have weak amplitudes and low signal-to-noise ratios.

Controls on paleokarst heterogeneity. Integrated study of the Upper Permian syngenetic karst in Rattlesnake Canyon, Guadalupe Mountains, USA [PDF]

, 2011
[eng] The present study contributes to a better understanding of early dissolution mechanisms for syngenetic karst development and provides constraints on the timing of formation of the Rattlesnake Canyon paleokarst system in the Guadalupe Mountains, New
